Camera Housing with External Positioning Elements
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional camera systems face challenges in accurately positioning image sensors relative to optical components without direct contact, which can lead to dirt contamination and increased installation tolerances.
Innovation Solution
A housing design with an outer receiving recess allows for the placement of positioning elements to define a support plane for the image sensor, enabling precise positioning without direct contact and reducing installation tolerances, using pin-shaped elements with rounded ends for enhanced flexibility.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If the image sensor is positioned directly in contact with the housing interior, then installation is simpler, but dirt contamination occurs and manufacturing precision deteriorates
Solution Approach 1:
The patent introduces positioning elements as intermediary components between the housing and the image sensor. These positioning elements feature rounded ends that contact the image sensor without requiring direct housing-sensor contact, thereby maintaining positioning precision while preventing dirt contamination. The positioning elements act as mediators that transfer the positioning function without the harmful direct contact.
2Manufacturing precision
If positioning elements are mounted inside the housing interior, then positioning is achieved, but particles are released and soil the housing interior and image sensor
Solution Approach 1:
The patent extracts the positioning elements from the housing interior and relocates them to the housing exterior. The positioning elements are mounted on the outside surface of the housing, and only their contact surfaces (rounded ends) extend toward the image sensor. This extraction eliminates the source of particle contamination while preserving the positioning function.
3Manufacturing precision
If the housing geometry is customized for direct image sensor placement, then positioning is precise, but device complexity increases and adaptability decreases
Solution Approach 1:
The patent makes the positioning elements universal components that can be applied to various housing geometries without requiring custom housing designs. The positioning elements with rounded ends provide a standardized interface that works with different housing shapes and sizes, thereby reducing device complexity while maintaining positioning precision through the external mounting approach.

AI summary
A housing for mounting a component that includes an image sensor, a fixed installation space being provided in the interior of the housing for accommodating at least one optical component. The housing has at least one outer receiving recess that is spatially separate from the interior of the housing. This outer receiving recess is provided for receiving at least one positioning element in a way that allows the positioning element to define a support plane relative to the housing, and the component including the image sensor to be placed on the positioning element, so that the component including the image sensor resides in the defined support plane. In this case, the component including the image sensor may be placed in the defined support plane in a way that does not allow any direct contact between the component that includes the image sensor, and the housing.
